Comparative Study Observational StudyPrediction of Bleeding after Cardiac Surgery: Comparison of Model Performances: A Prospective Observational Study.
Primary aims were to (1) perform external validation of the Papworth Bleeding Risk Score, and (2) compare the usefulness of the Dyke et al universal definition of perioperative bleeding with that used in the Papworth Bleeding Risk Score. A secondary aim was to use a locally developed logistic prediction model for severe postoperative bleeding to investigate whether prediction could be improved with inclusion of the variable "surgeon" or selected intraoperative variables. ⋯ Prediction of risk for excessive bleeding after cardiac surgery was not possible using clinical variables only, independent of endpoint definition and inclusion of the variable "surgeon" or of selected intraoperative variables. These findings may be due to incomplete understanding of the causative factors underlying excessive bleeding.
